Once-ever skill letting a new adherent follow their Bijou's light tendril straight to the strongest connected temple.
Welcome Home is granted immediately upon conversion by four of the fifteen light deities of the Ascendency pantheon, including Theia and Khepri. It can usually only be used once — ever. Combined with Travel the Path, it lets the adherent follow the tendril of light a Bijou fairy attached to their heart directly back to the strongest connected temple, which from the third floor to The Eleventh Floor is invariably inside Club Vanquisher.
Crucially, the spell still works even if the entrance to the temple has been destroyed — which is why blowing the doors on Club Vanquisher never sealed the hole Princess Vinata keeps slipping through. Rosetta built her whole theory of the naga escape trick around this skill.
The once-in-a-lifetime homing skill that makes a destroyed temple entrance irrelevant.
